Infiltration and Drainage Model The infiltration and drainage model developed by Texas A&M University (Liu and Lytton, 1984) can be used to evaluate the effects of rainfall on the degree of saturation and the resilient moduli of the base course and sub-grade. The degree of saturation for the base and the sub-grade is predicted daily by considering : the probability distribution of the amount of rainfall, the probabilities of wet and dry days, the infiltration of water into the pavement through cracks and joints, the drainage of the base course, and the wet and dry probabilities of pavement sub layers.

Infiltration and Drainage Model Under a FHWA contract, Texas A&M University is in the process of upgrading the infiltration and drainage model . A research study has been initiated by the FHWA to combine the CMS model, the infiltration and drainage model, and the frost model, which is a mathematical model of coupled heat and moisture flow in soils developed by the Cold Regions Research and Engineering Laboratory (Johnson et a1.,1986) .

Structural Models Report 1-26 recommended the use of elastic layer programs (ELP) and the ILLIPAVE finite element program for the development of a future AASHTO design guide. It suggested the use of the modulus depth relationship obtained from ILLI-PAVE to establish the various moduli for the ELP, thus capitalizing on the stress-sensitive feature of ILLI-PAVE and the multiple wheel capability of ELP .
